hi. first post here.
i have a 02 mp5 and its been sitting for the last two years ever since i got my passat. i just never got around to driving it because it needed a few things here and there to be fixed, but finally, my wife needed it for work so i got on the ball and got it running. i changed the front rotors and pads, new battery, and she was good to go. took it and had it inspected and it passed, no problems. this was on saturday. now, starting on sunday, the check engine light came on and it is really rocky at an idle and sounds like it wants to die. searching the net i found this post, which has had a ton of info for me to take in! Im pretty sure the EGR is in need of some serious cleaning, so i planned on doing that tonight.
However... upon going out, popping the hood and trying to take the intake tube off, i noticed that the accordion part of the intake tube had some places that were pretty much dry-rotted and were very brittle. it already had some holes in it, but when i was twisting the tube (before i noticed all of this) i think i made a bigger one in it. Im guessing this is bad....
Im gonna go ahead and pull the EGR and clean it since im this far in, but i was just wondering if when i put everything back together it will be drivable. the holes arent huge, the biggest one being maybe an inch or two. they are actually slits, rather than holes, in between the ridges in the pipe. im guessing that alone could cause an idle problem. any idea how much a replacement costs? i have found all the cold air ones for a couple-hundered dollars but im kinda broke at the moment and really need the car to function tomorrow! yikes! If the factory one isnt too expensive i could try and pick on up at my local dealer tomorrow because it looks like the autoparts stores dont carry stock replacements.
anyway, i just thought id post this up real fast while i go do the EGR cleaning. hopefully ill get some sort of response between now and the time im done.
